OPTISONIC 7300

Robust Material Construction: Measuring tubes available in 316L stainless steel or carbon steel (A106 Gr. B / A333 Gr. 6), paired with NACE-approved Grade 29 titanium transducers (optional Inconel or composite for hydrogen/oxygen service).

Broad Operating Envelope: Handles process pressures up to 431 barg / 6266 psig and temperatures ranging from -40°C to +180°C (-40°F to +356°F).

Integrated Volume Correction: Built-in flow computer capability converts actual volume flow to standard conditions using current inputs from external pressure and temperature transmitters.

Versatile Communications & Outputs: Features 3x 4…20 mA analog outputs, pulse/frequency/status discrete outputs, and HART®, Modbus RTU, or FOUNDATION™ Fieldbus protocols.

Embedded OPTICHECK Diagnostics: Provides continuous device status monitoring, parameter checks, and single-click on-site verification reporting without process interruption.

Hazardous Area Approvals: Certified for global safety standards including ATEX, IECEx, cQPSus, NEPSI, INMETRO, FM, CSA, and PESO.

Zero Pressure Loss & Energy Savings: The full-bore design presents no restrictions in the pipe, eliminating pressure drop and significantly lowering pumping and compression energy costs.

Maintenance-Free Reliability: With no moving parts or mechanical components subject to wear, maintenance overhead and operational downtime are virtually eliminated.

Hydrogen-Ready & Versatile: Reliable measurement across a broad spectrum of gases—including green hydrogen, natural gas, flue gas, compressed air, and hydrocarbon vapors—over a 100:1 turndown ratio.

Process Adaptability: Patented transducer geometry counteracts acoustic noise and density changes, guaranteeing consistent accuracy even under fluctuating flow conditions.

Simplified Compliance & Auditing: Integrated diagnostic tools streamline predictive maintenance and simplify quality compliance through verifiable, downloadable status reports.

Measurement Principle: Ultrasonic 2-path transit time differential measuring principle.

Measured Media: Natural gas, hydrogen, process gas, utility gas, compressed air, flue gas, steam, and hydrocarbon vapors.

Flow Performance: Bi-directional flow measurement with a dynamic range (turndown ratio) of up to 100:1.

Operating Pressure: Maximum 431 barg / 6266 psig (flange ratings up to PN450 / ASME Class 2500).

Operating Temperature: -40°C to +180°C (-40°F to +356°F).
